|Chromone glycosides from Knoxia corymbosa.[Pubmed: 17135054]|
|Four new chromone glycosides, corymbosins K1-K4 (3-6), together with two known compounds, Noreugenin (1) and undulatoside A (2), were isolated from the whole plant of Knoxiacorymbosa (Rubiaceae). |
METHODS AND RESULTS:
The structures of the new compounds were established through extensive NMR or X-ray spectroscopic analysis as 7-O-beta-D-allopyranosyl-5-hydroxy-2-methylchromone (corymbosin K1, 3), 7-O-beta-D-6-acetylglucopyranosyl-5-hydroxy-2-methylchromone (corymbosin K2, 4), 7-O-[6-O-(4-O-trans-caffeoyl-beta-D-allopyranosyl)]-beta-D-glucopyranosyl-5-hydroxy-2-methylchromone (corymbosin K3, 5) and 7-O-[6-O-(4-O-trans-feruloyl-beta-D-allopyranosyl)]-beta-D-glucopyranosyl-5-hydroxy-2- methylchromone (corymbosin K4, 6). Compounds 2-5 were subjected to test their immunomodulatory activity invitro.

||Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C).
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
Need more advice on solubility, usage and handling? Please email to: firstname.lastname@example.org
||The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.

|New Chromone Alkaloids from the Stem Bark of Schumanniophyton magnificum.[Pubmed: 17265261]|
|Fractionation of a methanolic extract of the stem bark of SCHUMANNIOPHYTON MAGNIFICUM yielded large quantities of mannitol. In addition, Noreugenin and ten related chromone alkaloids were isolated. Seven of these alkaloids had been isolated previously from S. MAGNIFICUM and one other from S.PROBLEMATICUM but two of the alkaloids were novel, one was hydroxy- N-methylschumannificine and the other was the acetate of N-demethylrohitukine. The structures of the two alkaloids have been deduced from their spectral features.|
